[Acute abdomen in pregnant woman treated for bariatric surgery for obesity: case report].

Bariatric surgery is currently considered as an alternative for the treatment of morbid obesity refractory to conventional clinical treatments. The surgeries more frequently used, which are radical and invasive, yield better and faster results, but are subject to clinical and surgical complications such as intestinal obstructions and subocclusions. Pregnancies in women submitted to this type of surgery are increasingly frequent, and the related complications have been increasingly reported.

Optical properties of vanadium dioxide and vanadium pentoxide thin films.

Several oxides of vanadium undergo a transition from a semiconductor or insulating state to a metal phase at a critical temperature. Vanadium dioxide undergoes this transition near 68 degrees C, while V(2)O(5) undergoes a similar phase transition near 257 degrees C. During the transition a change in oxide crystal structure is accompanied by large changes in electrical and optical behavior.
